ABSTRACT
PURPOSE: In major burns, deep vein thrombosis (DVT) is frequently diagnosed as a major complication of burns. But the risk factors and prophylaxis remain controversial. This study was designed to evaluate the incidence and risk factors of DVT in major burn patients. METHOD: We reviewed all major burn patients (>40% of TBSA) admitted to our burn center from June 1998 to August 2003 and assessed each affected patients with an in-hospital diagnosis of DVT for DVT risk factors. RESULT: There were 9 symptomatic DVT detected among 606 severe burn patients (1.45% incidence). Patients diagnosed with DVT had no risk factors of morbid obesity, previous DVT, congestive heart failure or neoplastic disease, except one patient who had a polycythemia vera diagnosed incidentally. In eight of 9 patients, DVT occurred in veins draining burned extremities. All patients had burn wound infections as a complication of burns. Eight of 9 patients had longer hospital stays than patients without DVTs. In all patients, DVT was developed after operations for skin graft. CONCLUSION: DVT should be suspected in patients with delayed wound healing and unresolved edema of extrimites. Wound infection, long bed-ridden state and operations are significant risk factors for DVT formation in major burn patients.
